Frequently asked

What water filter does a RF27CG5100SRAA refrigerator use?

The RF27CG5100SRAA uses the HAF-QIN water filter.

Does the HAF-QIN remove lead?

Yes - the HAF-QIN is NSF/ANSI 53 certified to reduce lead.

Should I buy the OEM filter or an aftermarket one?

The OEM HAF-QIN is the safe, exact-fit choice. A cheaper aftermarket filter can fit the same slot too - just confirm it carries its own independent NSF certification for the contaminants you care about, since a generic aftermarket filter without certification isn't proven to remove anything.

How often should I replace the HAF-QIN?

About every 6 months, or sooner if your fridge's filter-change indicator lights up or flow slows down.

Where is the water filter on a RF27CG5100SRAA?

Location varies by fridge design - commonly inside the fridge compartment (upper right or lower kickplate/grille) or in the water line behind the unit. Check your owner's manual for the exact spot on this model.
